The problem is that people need to use some rooms for multiple purposes, and these different functions call for varying amounts of light. Enter the dimmer switch, a handy electrical component that lets you adjust light levels from nearly dark to fully lit by simply turning a knob or sliding a lever.
Dimmers are devices used to vary the brightness of a light. By decreasing or increasing the RMS voltage and hence the mean power to the lamp it is possible to vary the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control lighting.
Different kinds of dimmers, touch dimmer, rotary dimmer ,and slide-to-off dimmer, are compatible with our LED rope lights.
With a dimmer, the LED rope light can be adjusted to the different brightness.

Dimmers range in size from small units the size of a normal light switch used for domestic lighting to high power units used in large theatre or architectural lighting installations. Small domestic dimmers are generally directly controlled, although remote control systems (such as X10) are available. Modern professional dimmers are generally controlled by a digital control system like DMX or ethernet.
